Laparoscopic resection of two liver hemangiomata.

New laparoscopic instrumentation coupled with standard surgical techniques allows one to perform procedures previously thought impossible via the laparoscope. This report reviews the natural history, the indications for resection, and the technique of laparoscopic resection of hepatic hemangiomata. Two women, 24 and 62 years of age, were first seen with abdominal pain. A diagnosis of hemangioma was made in each case, and both lesions were removed laparoscopically. Operative blood loss was 200 cc in each case, and neither patient required transfusion. Diets were started on the first postoperative day (POD), and the patients were discharged on the second and fourth PODs without narcotic analgesia. If the size and location of the tumor are favorable, laparoscopic resection of liver hemangiomata can be performed safely. Blood loss comparable to that of open procedures and a quicker recovery support an endosurgical approach to resection of liver hemangiomata in selected cases.

Malignant fibrous histiocytoma of the gastrointestinal tract in a patient with neurofibromatosis.

Malignant fibrous histiocytoma (MFH) of the gastrointestinal tract is extremely rare. A case of MFH of the colon associated with neurofibromatosis is presented. MFH is a high-grade soft-tissue sarcoma of fibroblast cell origin with a strong propensity for metastasis and recurrence. Immunochemical markers help to differentiate MFH from other sarcomas. The most successful treatment of MFH is surgical extirpation. Adjuvant chemotherapy and radiotherapy have not been definitively shown to be of value.

Hydrothorax as a late complication of central venous indwelling catheters.

Two cases of delayed onset hydrothorax following central venous catheterization are reported. Both involved left internal jugular vein percutaneous insertion sites, and chest roentgenograms of both demonstrated that the catheter tips were juxtaposed against the superior vena cava wall. Although both catheters functioned well for several days, we believe that this left neck site allowed for catheter tip motion, resulting in delayed perforation of the vessel. To avoid this complication we recommend that central venous catheters be checked routinely for position, with the catheter tip being parallel to the vessel wall. The left neck approach should be avoided if possible because of anatomic and mobility problems. These cases emphasize the fact that hydrothorax can occur long after successful catheter insertion, and they demonstrate the need to have continued suspicion of the possibility of this occurrence.

Acute cholecystitis as a complication of sarcoidosis.

Although sarcoidosis has been described affecting almost all body systems, acute cholecystitis has not previously been documented. Such a case is presented with a review of other gastrointestinal tract manifestations of the disease.

Extraordinary hyperbilirubinemia in a neonate with idiopathic hypertrophic pyloric stenosis.

This case describes an extraordinarily elevated total bilirubin level that reverted to normal 9 1/2 wk after Fredet-Ramstedt pyloromyotomy. Although the etiology of jaundice occurring in patients with IHPS remains uncertain, theories implicating inhibition of the glucuronyl transferase system have been proposed. Infants with IHPS have a documented hypergastrinemia. An hypothesis is offered, illustrated by this case, to explain the inhibition of the glucuronyl transferase system with resultant hyperbilirubinemia by the hypergastrinemia of idiopathic hypertrophic pyloric stenosis.
